A polydiacetylene coating layer deposited upon an organic microcrystal. The coating has a large, uniform surface area which is monoriented and without cracks. The preferred embodiment utilizes for the monomer a layer of [1,6-di- n(carbazolyl)-2,4-hexadiyne] deposited by epitaxy onto an acid orthopht ...
