The present disclosure is directed to novel germanosilicate compositions and methods of producing the same. In particular, this disclosure describes new silica-rich compositions of the germanosilicate designated CIT-13, with and without added metal oxides. The disclosure also describes methods of preparing and using these new germanosilicate compositions as well as the compositions themselves.

Phyllosilicate compositions designated CIT-13P and methods of preparing the same

The present disclosure is directed to novel germanosilicate compositions and methods of producing the same. In particular, this disclosure describes an array of transformations originating from the extra-large-pore crystalline germanosilicate compositions, designated CIT-13, possessing 10- and 14-membered rings. Included among the new materials are the new phyllosilicate compositions, designated CIT-13P, new crystalline microporous germanosilicates including high silica versions of CIT-5 and CIT-13, with and without added metal oxides, and new germanosilicate compounds designated CIT-14 and CIT-15. The disclosure also describes methods of preparing these new germanosilicate compositions as well as the compositions themselves.

Germanosilicate compositions and methods of preparing the same

The present disclosure is directed to novel crystalline germanosilicate compositions and methods of producing the same. In particular, the crystalline germanosilicate compositions are extra-large-pore compositions, designated CIT-13 possessing 10- and 14-membered rings. The disclosure describes methods of preparing these compositions using substituted benzyl-imidazolium organic structure-directing agents (OSDAs). Also disclosed are methods of using these crystalline compositions.

Crystalline germanosilicate materials of new CIT-13 topology and methods of preparing the same

The present disclosure is directed to the use of novel crystalline germanosilicate compositions in affecting a range of organic transformations. In particular, the crystalline germanosilicate compositions are extra-large-pore compositions, designated CIT-13 possessing 10- and 14-membered rings.

Disclosed is a method for detecting nucleic acids by promoting branched DNA complex formation. The target nucleic acid detection signal and sensitivity can be dramatically increased by promoting self assembly of branched DNA between a plurality of amplified DNA targets and a single-chain oligonucleotide probe, by means of the integrated implementation of PCR, thermal denaturation and hybridization in a single reaction mixture.
