Recent Advances in Applications of Fluorescent Perylenediimide and Perylenemonoimide Dyes in Bioimaging, Photothermal and Photodynamic Therapy

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(7), P. 6308 - 6308

Published: March 27, 2023

The emblematic perylenediimide (PDI) motif which was initially used as a simple dye has undergone incredible development in recent decades. increasing power of synthetic organic chemistry allowed it to decorate PDIs achieve highly functional dyes. As these PDI derivatives combine thermal, chemical and photostability, with an additional high absorption coefficient near-unity fluorescence quantum yield, they have been widely studied for applications materials science, particularly photovoltaics. Although always the spotlight, their asymmetric counterparts, perylenemonoimide (PMI) analogues, are now experiencing resurgence interest new efforts create architectures equally exciting properties. Namely, exceptional properties recently develop novel systems bioimaging, biosensing photodynamic therapy. This review covers state art synthesis, photophysical characterizations reported demonstrating versatility two sister PMI compounds. objective is show that after well-known emerging trends use PDI- PMI-based concern very specific biomedicinal including drug delivery, diagnostics theranostics.

Published: March 21, 2023

This work covers the development of non-fullerene acceptors for use in organic photovoltaics built using N-annulated perylene diimide dye. The classic dye has been extensively used to construct acceptors, leading device power conversion efficiencies over 10%. Strong visible light absorption and deep frontier molecular energy levels have made such materials (both polymeric) near ideal pairing with narrow-gap conjugated polymers bulk-heterojunction active layers. N-annulation provides an extra site side-chain engineering alters electronic structure polycyclic aromatic core. In addition, allows selective bromination core, building blocks that are useful construction large frameworks atom-economical direct heteroarylation cross-coupling method.

Long-Term Stable Organic Solar Cells through Amphiphilic Additives

ACS Applied Electronic Materials, Journal Year: 2024, Volume and Issue: 6(4), P. 2258 - 2267

Published: April 8, 2024

Organic solar cells have recently experienced tremendous efficiency improvements, but their longevity is still limited by morphological degradation, among other factors. We demonstrate in this work that small amounts of amphiphilic molecules such as perylene monoimide-diamine (PMIDA-C12) admixed to the active layer can dramatically improve classical polymer (P3HT:PC60BM). While fill factors and efficiencies reference without amphiphile dropped 35 4% original values after 588 h artificial aging (at 80 °C), respectively, these are stable at 80% initial for containing 0.01 wt % PMIDA-C12. Spectroscopic atomic force microscopy studies indicate amphiphiles stabilize morphology layers. Hence, presented approach doping with an molecule appears be promising improving long-term stability organic cells.
