Three novel silicon photosensitizers (PSs) are discovered with prospects to be utilized in psoralen ultra‐violet A (PUVA) cancer therapy, at B3LYP/6‐311++G** level of theory. They include 5‐methoxysilolo[3,2‐ g ]chromen‐2(8 H )‐one ( 1 ), 5‐methoxybenzo[4,5]silolo[3,2‐ g ]chromen‐2(10 H )‐one ( 2 ), and 11‐methoxybenzo[ c ]silolo[3,2‐ g ]chromen‐5(8 H )‐one ( 3 ). Structures 1 ‐ 3 exhibit intense narrow absorption peaks in the ultra violet A (UVA) therapeutic window and show T 1 energies necessary to activate the ground state triplet molecular oxygen ( 3 O 2 ) to its singlet excited state ( 1 O 2 ).
