DIBENZO[D,B]SILOLE-BASED REACTIVE MESOGENS

The present invention provides a compound of Formula (I) D-S1-A-S2 B1, Formula (I) wherein a represents a conjugated chain of from 1 to 20 aromatic moieties independently selected from the group consisting of aromatic moieties, heteroaromatic moieties and E moieties, provided that A includes at least one E moiety, wherein E is selected from the group consisting of E1 being a dibenzo[d,b]silole moiety of the structure, E2 being a moiety of the structure and E3 being a moiety of the structure wherein E is connected in the conjugated chain of A and optionally to S1 or to S2 through covalent bonds at Y and Z; wherein each R is independently selected from the group consisting of straight chain or branched C1-C20 alkyl and C2-C20 alkenyl, optionally wherein from 1 to 5 CH2 groups are each replaced by an oxygen, provided that no acetal, ketal, peroxide or vinyl ether is present in the R group, and optionally wherein each H bonded to a C in each R group may independently be replaced by a halogen; wherein the X moieties are the same and are selected from the group consisting of hydrogen, straight chain or branched C1-C8 alkyl, straight chain or branched C1-C8 alkoxyl and a halogen, wherein each E moiety may have the same or different X moieties, wherein W is either an oxygen or sulfur atom, D represents a moiety having one or more cross-linkable functionalities, S1 and S2 are flexible linker groups; and B1 represents a moiety having one or more cross-linkable functionalities or a hydrogen atom, with the proviso that when B1 represents a hydrogen atom, D represents a moiety having at least two cross-linkable functionalities.

Facile synthesis of a hole transporting material with a silafluorene core for efficient mesoscopic CH3NH3PbI3 perovskite solar cells

A novel electron-rich small-molecule, 4,4′-(5,5-dihexyl-5H-dibenzo[b,d]silole-3,7-diyl)bis(N,N-bis(4-methoxyphenyl)aniline) (S101), containing silafluorene as the core with arylamine side groups, has been synthesized via a short efficient route. When S101 was incorporated into a CH3NH3PbI3 perovskite solar cell as a hole transporting material (HTM), a short circuit photocurrent density (Jsc) of 18.9 mA cm-2, an open circuit voltage (Voc) of 0.92 V, and a fill factor (FF) of 0.65 contributing to an overall power conversion efficiency (PCE) of ～11% which is comparable to the PCE obtained using the current state-of-the-art HTM 2,2′,7,7′-tetrakis(N,N′-di-p-methoxyphenylamine)-9,9′-spirobifluorene (spiro-OMeTAD) (η = 12.3%) were obtained. S101 is thus a promising HTM with the potential to replace the expensive spiro-OMeTAD due to its comparable performance and much simpler and less expensive synthesis route.

Poly(2,7-dibenzosilole): A blue light emitting polymer

2,7-Disubstituted dibenzosilole monomers have been prepared by the selective trans-lithiation of 4,4′-dibromo-2,2′-diiodobiphenyl followed by silylation with dichlorodihexylsilane. Suzuki copolymerization of dibromo and bis(boronate) monomers afforded poly(9,9-dihexyl-2,7-dibenzosilole) which showed better efficiency than the corresponding polyfluorene in a single layer light emitting device. Preliminary studies demonstrated this to be a promising blue light emitting polymer. Copyright
