Novel propeller-like phosphorus containing compounds

Phosphorus compounds in animal tissues; the distribution of nucleic acids and other phosphorus-containing compounds in normal and malignant tissues.

Malignant tissues are distinguished from other types of tissues by their capacity for relatively unlimited and uncontrolled growth in the organism. The reason why neoplastic tissues grow continually, in contrast to embryonic tissues which grow only up to a certain point before they begin to differentiate, is a fundamental problem of cancer research. A study of the synthetic mechanisms of the ce...

A propeller-like uranyl metallomesogen.

Uranyl triflate forms with three imidazo[4,5-f]-1,10-phenanthroline ligands a propeller-like complex that exhibits a hexagonal columnar phase. The ligand is not liquid-crystalline, but a mesophase is induced upon complex formation with the uranyl salt. The thermal behavior has been investigated by polarizing optical microscopy and by high-temperature X-ray diffraction. A model of the stacking o...

Biocompatible Phosphorus Containing Photopolymers

Radical photopolymerization is the key technique to prepare films and coatings in an environmentally friendly way within the fraction of a second. During the last decade this technique has found access to many other categories, as for example rapid prototyping, manufacturing of printed circuits boards, dental filling materials and other biomedical applications. Photopolymers display several adv...

Phosphorus Compounds in Animal Tissues

The concept that nucleic acids are intimately associated with fundamental cellular processes has gained considerable favor within the last few years. This can undoubtedly be attributed to the researches of Caspersson and his associates. Caspersson, with the aid of ultraviolet spectrophotometry, has been able to measure the nucleic acids in various parts of the cell under a variety of experiment...
