Thermal Bergman cyclization of Pt(ii) dialkynylporphyrins reveals a marked reduction in the cyclization temperature relative to the free base and Zn(ii) derivatives. In contrast, photogenerated 3ππ* population produces no detectable Bergman photocyclization, suggesting that the photoreactivities of the related free base and Zn(ii) derivatives occurs via the 1ππ* state.
