Abstract
An electrochromic device includes a cathodic compartment including a cathodic material; an anodic compartment including an anodic material; and a transparent, ion-selective membrane displaced between the cathodic compartment and the anodic compartment wherein the transparent, ion-selective membrane is a cationic polymer.
Claims19
A cationic polymer represented by Formula I, Formula II, or Formula Ill:
- wherein:
- each R1 may be individually alkylene, cycloalkylene, or heterocycloalkylene;
- R2 may be H;
- each R3 may be individually absent, —O—, or -alkyl-;
- each R3a may may be individually -alkyl-;
- each R4 may be individually alkylene, cycloalkylene, or heterocycloalkylene;
- each R5 may be individually absent or alkylene, cycloalkylene, or heterocycloalkylene;
- each R6 may be individually absent or alkylene;
- each R7 may be individually a group of formula:
- —[P(R13)3]+;or —[N(R11)3]+;
- R8 is alkyl, cycloalkyl, or heterocycloalkyl;
- each R9 is individually H, F, Br, CI, NO2, alkyl, cycloalkyl, alkoxy, aryl, or heteroaryl, or any two individual R9 groups may join together to form a ring which may be saturated or unsaturated;
- each R1° is individually H, F, Br, CI, NO2, alkyl, cycloalkyl, alkoxy, aryl, or heteroaryl, or any two individual R1° groups may join together to form a ring which may be saturated or unsaturated;
- each R11 is individually H, alkyl, cycloalkyl, aryl, or heteroaryl, or any two individual R11 groups may join together to form a ring which may be saturated or unsaturated;
- each R12 may be individually H or alkyl;
- each R12 may be individually alkyl or aryl;
- each Cat is a cationic group;
- each X−is individually an anion;
- each n, p, and r1-5 indicate a repeat unit of the polymer;
- each q may be individually 1, 2, or 3;
- individually T is individually absent, C(O), or CH2;
- and
- individually T′ is individually absent or C(O).
