Abstract By modifying a synthetic procedure, two new hyperbranched polytriazoles ( HP1 and HP2 ) containing isolation chromophores were synthesized successfully through click chemistry reactions under copper(I) catalysis. For the first time, these two polymers were derived from an AB 4 ‐type monomer, although they contain different end‐capping chromophores. They are soluble in normal polar organic solvents and are well characterized. Thanks to the presence of the isolation chromophore, the two polymers demonstrate good nonlinear optical (NLO) properties and optical transparency, making them promising candidates for practical applications.
