Abstract

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 suqare planar geometry and multiple sites of coordination with an anion-exchange resin. The novel catalyst can be made by forming an acid salt derivative of the transition metal complex and mixing it together with an anion-exchange resin. Addition of the novel catalyst is added to a strained cyclic non-conjugated carbon containing compound results in the release of heat energy through the conversion of the non-conjugated carbon containing compound to its conjugated form. The non-conjugated carbon containing compound and the catalyst may be in compartments in a sealed container means which 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 is also provided wherein the conjugated carbon containing compound is exposed to radiant energy and is converted to the non-conjugated form and the non-conjugated form is then combined with the novel catalyst converting the non-conjugated form to the conjugated form and resulting in the release of heat energy which is collected.
