2,2'- [[12,13-Bis(2-butyloctyl)-12,13-dihydro-3,9-dinonylbisthieno[2'',3'':4',5']thieno[2',3':4,5]pyrrolo[3,2-e:2',3'-g][2,1,3]benzothiadiazole-2,10-diyl]bis[methylidyne(5,6-chloro-3-oxo-1H-indene-2,1(3H)-diylidene) ]]bis[propanedinitrile]
BTP-eC9 is a family member of the Y series of n-type non-fullerene semiconducting acceptors. It has been proven that these NFAs can achieve high device performance in non-fullerene polymer solar cells (NF-PSCs).We have sublimation apparatus

With a fused thienothienopyrrolo-thienothienoindole (TTP-TTI) core, BTP-eC9 is a modified version of Y7 but with better solubility. Comparing to Y6, chlorination at the peripheral end-groups can efficiently lower HOMO/LUMO energy levels. C–Cl bond also has a large dipole moment, expanding the absorption range further to near infrared (NIR) region.

A device efficiency approaching 18% has been reported using BTP-eC9 as the electron acceptor and PBDB-T-2F (PM6) as electron donor in single junction organic photovoltaic cells.
