摘要

Tetrabenzoylgermane 1 and various substituted tetrabenzoylgermanes 2-7 were investigated as visible light (VL) photoinitiators (PIs) for dental dimethacrylate resins and dimethacrylate-based composites. The tetrabenzoylgermanes 1-7 show a very strong VL absorption between 400 and 450 nm. Substituents on the benzoyl chromophore strongly influence their properties such as melting point, solubility, absorption behavior, or PI reactivity. A good photobleaching behavior and a very high reactivity as VL PI was found in photo-differential scanning calorimeter experiments for selected tetrabenzoylgermanes. Composite pastes containing only similar to 0.1 wt % of Ge-PI exhibited a sufficient photocuring due to the high PI-reactivity of the tetraacylgermanes. Among the investigated germane PIs, tetrakis(2-methylbenzoyl) germane 2 shows the best performance as VL PI for restorative composites and enables the composites to be photocured using an LED with an emission maximum of 500 nm.
