The synthesis and purification of amphiphilic conjugated donoracceptor block copolymers
Nanoscale domains of donor and acceptor materials are crucial for charge generation in organic photovoltaic devices. These domains are difficult to achieve reproducibly in blended materials, but could be engineered into single-material active layers composed of donor–acceptor block copolymers (BCPs). In this work, we report the synthesis and purification of two novel fully conjugated BCPs, P3HT...
متن کامل4-(4-Nitrobenzenesulfonamido)pyridinium trichloroacetate
In the crystal structure of the title compound, C(11)H(10)N(3)O(4)S·C(2)Cl(3)O(2), the dihedral angle between the two six-membered rings is 69.2 (1)°. The mol-ecules are connected via inter-molecular N-H⋯O hydrogen bonding.

In the title compound, C(11)H(10)N(3)O(4)S(+)·C(2)Cl(3)O(2) (-), the benzene ring forms an angle of 85.21 (13)° with the pyridinium ring. The nitro group is nearly coplanar with its attached benzene ring [dihedral angle = 3.68 (12)°]. In the crystal structure, strong N-H⋯O hydrogen bonds link the ion-pairs. The packing is further consolidated by weak C-H⋯O inter-ations.

In the title compound, C(11)H(10)N(3)O(4)S(+)·C(2)F(3)O(2) (-), the benzene ring makes an angle of 87.3 (2)° with the pyridinium ring. The nitro group is essentially coplanar with the benzene ring. The F atoms of the CF(3) group are disordered over two positions with almost equal occupancy [0.531 (12)/0.469 (12)]. The crystal structure is stabilized by N-H⋯O and C-H⋯O hydrogen bonds.

In the title compound, C(11)H(10)N(3)O(4)S(+)·Br(-), the benzene ring makes an angle of 88.4 (2)° with the pyridinium ring. The dihedral angle between the nitro group and the benzene ring is 16.5 (2)°. The ions in the crystal structure are linked by a combination of inter-molecular N-H⋯Br and non-conventional C-H⋯Br and C-H⋯O hydrogen bonds, forming a three-dimensional network.
