abstract = {Organic afterglow materials, known for their unique luminescent
properties and diverse applications, have garnered significant attention
in recent years. However, developing long-lasting, high-efficiency,
full-color afterglow systems and exploring simple materials processing
strategies for new applications are still challenging in this field.
Herein, we rationally design a processable molecular glass and employ it
as a host in a host-guest strategy to address these challenges. By
strategically modifying the host via othyl-methylation, we successfully
create a molecular glass and capture its temperature-dependent,
processable viscous supercooled liquid state. High-efficiency full color
from violet to near-infrared afterglow systems with ultralong lifetimes
are developed by doping varied structural dopants. The underlying
glass-forming and afterglow mechanisms are also clearly elucidated and
verified. Moreover, the excellent glass-forming ability of the host and
its viscous supercooled liquid enabled the glass system for large-area
fabrication, shaping of objects with diverse 3D structures, and creation
of flexible, meter-long afterglow fibers. This work offers significant
potential for practical applications in advanced textiles, displays, and
other fields.},

abstract = {Because of the rapid emergence of antibiotic-resistant bacteria, there
is a growing need to discover antibacterial agents. Here, we design and
synthesize a compound of TPA2PyBu that kills both Gram-negative and
Gram-positive bacteria with an undetectably low drug resistance.
Comprehensive analyses reveal that the antimicrobial activity of
TPA2PyBu proceeds via a unique dual mechanism by damaging bacterial
membrane integrity and inducing DNA aggregation. TPA2PyBu could provide
imaging specificity that differentiates bacterial infection from
inflammation and cancer. High in vivo treatment efficacy of TPA2PyBu was
achieved in methicillin-resistant Staphylococcus aureus infection mouse
models. This promising antimicrobial agent suggests that combining
multiple mechanisms of action into a single molecule can be an effective
approach to address challenging bacterial infections.},

abstract = {The ability of mechanoluminescent (ML) materials to convert mechanical
energy into visualizable patterns through light emission offers a wide
range of applications in advanced stress sensing, human-machine
interfaces, biomedical science, etc. However, the development remains in
its infancy, and more importantly, the reliance on specific crystalline
structures in most existing ML materials limits their processability and
practical utility. Here, we introduce a series of purely organic
amorphous ML materials incorporating flexible skeletons and twisted
donor-acceptor-acceptor' structures designed to enhance dipole moment
and flexibility. These materials exhibit multicolor ML in amorphous
states and possess low glass transition temperatures, allowing facile
and in situ regeneration and processing. The stress-induced short-range
molecular ordering within the amorphous phase generates local
piezoelectricity, enabling ML without crystallinity. This approach
overcomes the limitations of traditional crystalline ML materials,
facilitating the development of flexible ML films and expanding the
practical utility of organic ML systems.},

abstract = {Materials with room-temperature phosphorescence (RTP) from deep red to
near-infrared (NIR) region exhibit great potential for emerging
applications. However, such molecules typically require a low-lying
first triplet (T1) excited state, which may not be optimal for exciton
stabilization, potentially compromising the phosphorescence lifetime.
This study reports the design of four 9H-carbazole (Cz) analogs with
extended conjugation lengths used as dopants to achieve RTP emissions in
deep red and NIR regions with lifetimes exceeding 700 ms. These findings
reveal that substituting reactive hydrogen atoms in Cz analogs with
methyl groups significantly enhances the photoluminescence quantum yield
(PLQY) of these materials compared to their non-methylated counterparts.
Additionally, these doping systems can be activated by visible light,
achieving persistent phosphorescence even under the excitation of 450 nm
light. Theoretical calculations demonstrate the crucial roles of charge
transfer state and the enhanced spin-orbital coupling (SOC) matrix
elements upon doping for achieving long-lifetime phosphorescence beyond
600 nm. This research presents a strategy employing Cz-based doping
systems to facilitate RTP emissions extending from visible to deep red
and NIR regions.},

abstract = {Ultralong thermally activated delayed fluorescence (UTADF) materials
play an important role in realizing time-dependent color-tunable
afterglow. Some typical carbazole (Cz) derivatives have been reported to
exhibit UTADF properties. However, a 10-fold difference in TADF lifetime
was found between commercial Cz derivatives and the corresponding
lab-synthesized ones, which indicated that UTADF may not be derived from
the single Cz derivatives as reported. To reveal the real mechanism, we
synthesized three Cz derivatives and one isomer to form three host-guest
pairs for optical studies. The photophysical properties revealed that
UTADF originated from the intermolecular charge transfer between host
and guest, while the ultralong organic phosphorescence was from the
guest. Thanks to the rich color variations in luminescence displayed by

can be applied to realize multi-dimensional encryption in both delay

work to realize ultralong thermally activated delayed fluorescence
(UTADF). The results show that UTADF is derived from the intermolecular
charge transfer formed by host and guest, which is contradictory to the
previous reports that UTADF of carbazole derivatives was derived from a
specific molecular design. The difference in lifetime between UTADF and
ultralong organic phosphorescence enables time-dependent dynamic
afterglow. image},
