1221887-42-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1221887-42-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,8,8 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1221887-42:
(9*1)+(8*2)+(7*2)+(6*1)+(5*8)+(4*8)+(3*7)+(2*4)+(1*2)=148
148 % 10 = 8
So 1221887-42-8 is a valid CAS Registry Number.

Synthesis of bipolar charge transporting block copolymers and characterization for organic light-emitting diode

Tsuchiya, Kousuke,Kasuga, Hidemasa,Kawakami, Akira,Taka, Hideo,Kita, Hiroshi,Ogino, Kenji

experimental part, p. 1461 - 1468 (2011/02/25)

A series of hole and electron transporting random and block copolymers consisting of triphenylamine moiety as a hole transporting unit and oxadiazole moiety as an electron transporting unit have been prepared via a nitroxide mediated radical polymerization. Oxadiazole monomers with t-butyl or trifluoromethyl groups, 2 and 7, respectively, were used for copolymerization. Photoluminescent measurements of polymers revealed that the formation of the exciplex between triphenylamine and oxadiazole units tends to occur in the order of random copolymers, block copolymers, and polymer blends, implying phase-separated morphologies in block or blend systems. The polymers were applied for OLED devices, and we found that the morphology in the polymer layer critically affected device performance. The block copolymer comprising hole and electron transporting units with the composition of 14/86 showed the highest external quantum efficiency over 10%.
