A series of new macrocycles and cage-like molecules are obtained in a high yield from a bis-(2,4-dialkoxyphenyl)arene (naphthalene, anthracene, pyrene, porphyrin, etc.) or a tris-(2,4-dialkoxyphenyl)arene (benzene, sym-tribenzobenzene) and paraformaldehyde under the catalysis of a Lewis acid. In addition, perhydroxybiphenylarenes (tetrabiphenyl trimer, naphthalene dimer, etc.) can be obtained by means of demethylation, and a variety of water-soluble derivatives can be obtained by further modification, with same exhibiting a good bond ability for guest molecules (purpurine, etc.). Moreover, the functional group introduced into the backbone enables the macrocycle to have excellent adsorption and separation capabilities and a photophysical property. The macrocyclic and cage-like molecules have commercially available raw materials, are simple to synthesize, have a high yield, and are convenient to modify, such that same have wide application prospects in gas adsorption and separation, facilitate performance improvement of luminescent materials, perform adsorption of water-soluble toxic substances, etc.

The disclosure features novel lipids and compositions involving the same. Nanoparticle compositions include a novel lipid as well as additional lipids such as phospholipids, structural lipids, and PEG lipids. Nanoparticle compositions further including therapeutic and/or prophylactics such as RNA are useful in the delivery of therapeutic and/or prophylactics to mammalian cells or organs to, for example, regulate polypeptide, protein, or gene expression.

A method for synthesizing polyolefin materials with a controlled degree of branching includes the following steps: polymerizing cyclic olefin monomers under catalyst conditions. The cyclic olefin monomer is shown in formula I, where n≥0, n is an integer. By changing monomers and reaction parameters such as reaction temperature, solvent type, catalyst concentration, monomer concentration and reaction time, the degree of branching, the molecular weight and molecular weight distribution of polyolefin can be controlled. Compared with the existing process, the present invention is a new polymerization process, which can prepare the hyperbranched polyolefin with precise and controllable branching structure. The polyolefin material prepared according to the present invention has advantages of a controlled degree of branching, low viscosity and good fluidity, which has broad application in coating, lubricant, polymer and process flow improvement technologies.
