1223479-75-1 Usage
Uses
Used in Organic Photovoltaic (OPV) Solar Cells:PBDTTPD is used as a polymer semiconductor in OPV solar cells for its high device performance. The thieno[3,4-c]pyrrole-4,6-dione (TPD) unit provides a planar structure that promotes electron delocalization and enhances intrachain and interchain interactions. Its strong electron-withdrawing effect results in relatively low HOMO and LUMO energy levels for the polymer semiconductors, which is beneficial for solar cell efficiency.
Used in Field Effect Transistors:
PBDTTPD is also utilized in field effect transistors due to its conducting polymer properties and the ability to form a π-conjugating system, which is essential for the development of high-performance electrochemical devices.
Used in Organic High-Efficiency Photovoltaic Cells (PCE 6.8%):
PBDTTPD is employed in the development of organic high-efficiency photovoltaic cells, achieving a power conversion efficiency of 6.8%. The linear n-octyl side chain on the acceptor moiety allows for stronger electronic coupling with fullerene when integrated into OPV devices, further enhancing the performance of these solar cells.

The CAS Registry Mumber 1223479-75-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,3,4,7 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.Calculate Digit Verification of CAS Registry Number 1223479-75:
(9*1)+(8*2)+(7*2)+(6*3)+(5*4)+(4*7)+(3*9)+(2*7)+(1*5)=151
151 % 10 = 1
So 1223479-75-1 is a valid CAS Registry Number.
