Photochemistry related studies have been driven by with the application of new types of photocatalysis. Lately boron-dipyrromethene (BODIPY) as distinguished chromophore with exceptional photophysical and chemical features has emerged as a viable photosensitizer. Within this context, three new NDI-BODIPY triads (8-10) were synthesized/ characterized and used to investigate the efficiencies of singlet oxygen generation and oxidation of 1,5-dihydroxynapthalene to juglone under visible light. Singlet oxygen generation was determined both via indirect method by using 1,3-diphenylisobenzofuran as trap molecule and from the characteristic O phosphorescence at 1270 nm. Also, NDI with BODIPY dyes bearing bromine and iodine atoms were shown to be highly active photocatalysts in which the activities are comparable or higher to the readily available commercial systems where 36% (9) and 66% (10) juglone production was achieved under 15 min. This work may emphasize good example of applying NDI-BODIPY based triads as photocatalysts for a series of important organic transformations.
光化学相关研究一直受到新型光催化应用的推动。最近，硼二吡咯亚甲基（BODIPY）作为具有卓越光物理和化学特性的独特发色团，已成为一种可行的光敏剂。在此背景下，合成并表征了三种新型的NDI - BODIPY三联体（8 - 10），并用于研究在可见光下单线态氧的产生效率以及1,5 - 二羟基萘氧化为胡桃醌的情况。单线态氧的产生通过使用1,3 - 二苯基异苯并呋喃作为捕获分子的间接方法以及1270 nm处的特征O磷光来测定。此外，带有溴和碘原子的NDI与BODIPY染料被证明是高活性光催化剂，其活性与现有的商业体系相当或更高，在15分钟内可实现36%（9）和66%（10）的胡桃醌产量。这项工作可能为将基于NDI - BODIPY的三联体用作一系列重要有机转化的光催化剂提供了一个很好的例子。
