Three metal-free molecular photosensitizers (S1-S3) featuring a starburst triarylamine donor moiety have been synthesized. They show attractive photocatalytic performance in visible light-driven H2 production from water in their platinized TiO2 composites. A remarkable H2 turnover number (TON) of 10 200 (48 h) was achieved in an S1-anchored system.
