Compounds and methods that release 1-methylcyclopropene, 1-trifluoromethylcyclopropene, and other substituted cyclopropenes are disclosed. The compounds are of the class of chemical analogue of 2-oxa-bicyclo[2.1.0]penta-3-one useful as vessels for molecular plant ethylene receptor inhibitors. The compounds and methods overcome present limitations for storage, transportation, and application of the cyclopropene containing compounds by using light, including sunlight, and/or heat as the primary release trigger. Additional products released include innocuous gases and value added aryl-group compounds.
