    Abstract: \\ Novel catalyst for the photochemical conversion and storage of radiant energy through the conversion of strained cyclic non-conjugated carbon containing compounds to their corresponding conjugated forms comprises ionically bonding a transition metal complex having a square planar geometry and multiple sites of coordination with an anionexchange resin. A method is provided for the preparation of the novel catalyst and comprises forming an acid salt derivative of the transition metal complex and mixing it together with an anion-exchange resin. A process wherein the novel catalyst is added to a strained cyclic non-con-jugated carbon containing compound resulting in the release of heat energy through the conversion of the non-conjugated carbon containing compound to its conjugated form. A process and sealed container means wherein the nonconjugated carbon containing compound and the catalyst are in compartments and are separated until heat energy is required. The means of separation is then broken and the non-conjugated carbon containing compound is converted to the conjugated form with the release of heat energy. A process and apparatus wherein the conjugated carbon containing compound is exposed to radiant energy and is converted to the non-conjugated form. The non-conjugated form is then combined with the catalyst described hereinabove, converting the non-conjugated form to the conjugated form and resulting in the release of heat energy which is collected.
