A second generation of cyanine-based near-infrared photocatalysts has been developed to accelerate organic transformations. Cyanines were prepared and fully characterized prior to evaluation of their photocatalytic activities. Catalyst efficiency was determined by using two model oxidation and reduction reactions. For the aza-Henry reaction, cyanines bearing an amino group on the heptamethine chain led to the best results. For trifluoromethylation, the stability of the photocatalyst was found to be the key parameter for efficient and rapid conversion.
第二代基于花青的近红外光催化剂已被开发出来，以加速有机转化反应。在评估其光催化活性之前，先制备了花青并对其进行了全面表征。通过两个模型氧化和还原反应来确定催化剂效率。对于氮杂亨利反应，在七甲川链上带有氨基的花青产生了最佳结果。对于三氟甲基化反应，发现光催化剂的稳定性是高效快速转化的关键参数。
