Effective design of organic luminogens for near-infrared-II fluorescence imaging and photo-mediated therapy

Abstract

Organic luminogens possess excellent photonic features that are essential for biomedical applications.

Achievement of efficient thermally activated delayed fluorescence materials based on 1,8-naphthalimide derivatives exhibiting piezochromic and thermochromic luminescence

“…In recent years, organic luminescent materials have garnered extensive attention due to their widespread applications in photonic devices, 1,2 sensors, 3,4 bioimaging, [5][6][7] and therapeutics. 8,9 Among these materials, thermally activated delayed uorescence (TADF) materials have been particularly highlighted for their potential to achieve 100% internal quantum efficiency and to manufacture cost-effective organic lightemitting diodes (OLEDs).…”

Donor–Acceptor Engineering for Tailoring Highly Efficient Photosensitizers for Image-Guided Antitumor Photodynamic Therapy

“…Fortunately, the discovery of luminogens with the aggregation-induced emission (AIE) property has created a remedy to this challenge. After continuous efforts in designing numerous novel AIE systems, it is now well understood that, in the aggregate state, the intramolecular motions of AIE luminogens are largely restricted to allow the excited state to undergo radiative decay and give rise to strong emission . In contrast to traditional PSs, PSs with AIE features offer exceptional properties in the aggregate state, such as enhanced photosensitization and high brightness, which make them competent candidates for bioapplications …”
