Abstract
The present disclosure relates to a dimer that includes a first hydroxyl-functionalized naphthalene group and a second hydroxyl-functionalized naphthalene group, where the first hydroxyl-functionalized naphthalene group and the second hydroxyl-functionalized naphthalene group are connected by a bridging group. The present disclosure also relates to a polymer synthesized using the dimer, as well as methods for synthesizing both the dimer and the polymer.
Claims20
A dimer comprising:
- a first hydroxyl-functionalized naphthalene group;
- and
- a second hydroxyl-functionalized naphthalene group, wherein:
- the first hydroxyl-functionalized naphthalene group and the second hydroxyl-functionalized naphthalene group are connected by a bridging group.
A polymer comprising:
- a dimer comprising:
- a first hydroxyl-functionalized naphthalene group;
- and
- a second hydroxyl-functionalized naphthalene group, wherein:
- the first hydroxyl-functionalized naphthalene group and the second hydroxyl-functionalized naphthalene group are connected by a bridging group, wherein:
- the polymer contains between 2 and 1500 units of the dimer, and
- the bridging group comprises an aliphatic group.
A method comprising:
- reacting a precursor molecule with a first bridging molecule to form a dimer, wherein:
- the precursor molecule comprises a hydroxyl-functionalized naphthalene, and
- the first bridging molecule comprises at least one of a ketone, an aldehyde, or a halogenated aliphatic molecule.
A method for producing a dimer, the method comprising:
- reacting 2-naphthol with Br2 to produce 6-bromonaphthalen-2-ol;
- reacting the 6-bromonaphthalen-2-ol to produce 2-bromo-6-methoxynaphthalene;
- reacting the 2-bromo-6-methoxynaphthalene with magnesium to produce 6-methoxynaphthalene, 2-MgBr;
- reacting the 6-methoxynaphthalene, 2-MgBr with 2,3-dibromobutane to produce 2,2′-(1,2-dimethyl-1,2-ethanediyl)di-(6-methoxynaphthalene);
- and
- reacting the 2,2′-(1,2-dimethyl-1,2-ethanediyl)di-(6-methoxynaphthalene) to produce the dimer comprising 6,6′-(butane-2,3,-diyl)di(naphthalen-2-ol).
