1. A transparent electrochromic formed by polymerization of a diamine and a cycloaliphatic dianhydride,
wherein the diamine comprises a diamino triphenylamine having the formula Wherein R1 consists of hydrogen, halogen, C1-6 alkyl group, C1-6 alkoxy group, orand R2 consists of hydrogen, halogen, C1-6 alkyl group, C1-6 alkoxy group; and
the cycloaliphatic dianhydride comprises wherein the resulting polymer is sufficiently soluble in an organic solvent having a boiling point of 150° C. to 220° C. to form a film, and wherein the resulting polymer is configured to, when placed into a film, transfer from colorless to color upon application of a voltage.
