2-butyne-1,4-diol ( 1,4-bd ) is used as a divergent ditopic template that directs trans -1,2-bis ( n  - pyridyl) ethylene (  n  ,  n  ' -bpe , where n = n ' = 3 or 4) to undergo an intermolecular [2 + 2] photodimerization in the solid state. The components of cocrystals [( 1,4-bd )·( 4,4'-bpe )] n and [( 1,4-bd )·( 3,3'-bpe )] n form 1D hydrogen-bonded polymers with  n , n '-bpe assembled as infinite parallel stacks. The alkenes undergo [2 + 2] photocycloadditions to form rctt -tetrakis ( n -pyridyl) cyclobutane (where n = 3 or 4). We demonstrate that the reactive solid involving 4,4'-bpe exhibits supramolecular catalysis.
