Abstract

Easily accessible and inexpensive potassium carbonate (KCO) has been applied as the base-catalyst for the synthesis of novel classes of functionalized nanomaterials. This eco-friendly approach has been proven to be effective for a wide range of substrates, leading to nine isocyanate derivatives of silsesquioxanes (SQs) with yields exceeding 90% in mild and transition metal-free conditions. The application potential of chosen products was assessed on the basis of thermogravimetric analyses and photochemical measurements.

摘要

易于获取且价格低廉的碳酸钾（KCO）已被用作合成新型功能化纳米材料的碱催化剂。这种环保方法已被证明对多种底物有效，在温和且无过渡金属的条件下可得到九种倍半硅氧烷（SQs）的异氰酸酯衍生物，产率超过90%。基于热重分析和光化学测量对所选产物的应用潜力进行了评估。
