Abstract
Abstract Within series of Ln 3 -grafted polymers Poly({[Ln 3 (L) 4 (NO 3 ) 6 ]·(NO 3 )·(H 3 O) 2 }-co-NBE) (Ln = La, 1 ; Ln = Eu, 2 ; Ln = Tb, 3 ; Ln = Nd, 4 ; Ln = Yb, 5 ; Ln = Er, 6 or Ln = Gd, 7 ) obtained from ring-opening metathesis polymerization (ROMP) of norbornene (NBE) with each of allyl-functionalized complex monomers {[Ln 3 (L) 4 (NO 3 ) 6 ]·(NO 3 )·(H 3 O) 2 } ( HL = 4-allyl-2-(1 H -benzo[ d ]imidazol-2-yl)-6-methoxyphenol), PNBE-assisted effective energy transfer renders Poly(3- co -NBE) Tb 3+ -centered highly luminous color-purity green-light with an attractive quantum yield of 87% and efficient near-infrared (NIR) luminescence ( Φ Nd L = 0.61%; Φ Yb L = 1.47% and Φ Er L = 0.03%) for Nd 3+ -, Yb 3+ - or Er 3+ -grafted polymers.
