Abstract:
1. A method for growing a bulk single crystal of a configurationally locked polyene compound with a phenolic electron donor, the compound being represented by the formula (I): wherein n=1, 2, 3 or 4, wherein R1 and R2, being identical or different, are independently chosen from the group consisting of: H (Hydrogen), D (Deutrium), and any perhalogenated, halogenated or non-halogenated aliphatic or aromatic group, wherein at least one carbon atom of the aliphatic or aromatic group is optionally functionalized with at least one of: hydroxy, ether, ester, amino, silyl, and siloxy group, and wherein the method comprises the following steps: predefining at least one of a minimal crystal thickness and a thickness to side length ratio of the crystal; providing the compound solved in a solvent or as a melt; slowly evaporating the solvent or slowly cooling the solution or the melt; and growing the bulk single crystal, said step of growing comprising the sub-steps of:
