Abstract

BODIPY-based conjugated microporous polymers (BDP_CMP and PHTT_BDP) have been synthesised via two distinct methods of assembly: high-yielding Suzuki-Miyaura cross-coupling of BODIPY-containing building blocks, and post-synthetic conversion of an aldehyde-equipped CMP host that was synthesised in the absence of metal-based catalysts. Both approaches yielded BODIPY-based materials featuring high BET surface area (484-769 m2 g-1) and a bathochromic shift in the maximum light absorbance (520-550 nm). Singlet oxygen production employing the BODIPY-based materials at 530 nm was carried out heterogeneously in a commercial photochemical flow reactor.
