Aza-borondipyrromethenes (aza-BODIPYs) possess excellent photophysical properties, and the structurally modified dyes exhibit favourable performance and applications in biomolecular sensing, photoelectric materials, and tumor phototherapy.
Triphenylamine-functionalized NIR-absorbing aza-BODIPY dyes 1–3 were synthesized and their properties were investigated in detail. A PCE of 18.12% was achieved for the PSCs employing dye 1 as the dopant-free hole transporting material.
The reactivity of azadipyrromethenes towards a carborane S-nucleophile was studied, providing an efficient route for the synthesis of boronated aza-BODIPY derivatives.
A polymeric photosensitizer, based on biodegradable, biocompatible and water dispersible PBAE, has been developed. The photosensitizer exhibits potential for targeted anticancer activity and imaging, making it effective for photodynamic therapy.
The recent advances in the supramolecular assembly of BODIPY and aza-BODIPY dyes are reviewed, emphasizing the control over the kinetic pathway complexity of this class of dyes, and the prospects for future research are summarized.
