obtain benzo[c]coumarin bearing amino and nitro groups at various positions, which served as entry points to prepare complex hybrids of 1,4-benzoxazin-2-ones and benzo[c]coumarins. The hydroxyl group proved to be the synthetic handle, enabling the synthesis of strongly solvatochromic, soluble analogues. The effect of structural variation on photophysicalproperties was studied in detail for almost
