N , N '-octyl biphenothiazine and dibenzothiophene dioxide-based soluble porous organic polymer for biphasic photocatalytic hydrogen evolution.

A donor-acceptor-based soluble porous organic polymer (PzDBS) was fabricated using a flexible core composed of N , N '-octyl biphenothiazine and a rigid building unit involving dibenzothiophene dioxide. The soluble porous organic polymer was explored for aqueous-organic biphasic photocatalytic hydrogen evolution, introducing a promising avenue in the domain of porous polymer photocatalysts.
