Glass container coated internally with a metal-organic framework

A method of manufacturing a glass container including an inner wall and a coating of formula —Si—O—R-M-MOF covalently bonded to the inner wall in an inverted radial manner, where MOF is a metal-organic framework, where M is a metal dependent on a type of the MOF, and where R is an intermediate compound selected from the group consisting of:

• —Si—(CH2)3—NH—CH(═O)—(C6H4)—COO—;
• B) —Si—(CH2)n—NH—CH(═O)—(CH2)2—(C2HN3)—(CH2)n—(C6H4)—COO—;
• C) —Si—(CH2)n—O—CH2—CH(—OH)—CH2—NH—(CH2)n—(C6H4)—COO—;
• D) —Si—(CH2)n—S—(CH2)2—(CH2)n—(C6H4)—COO—, with an n which can take values between 0 and 6,
• the method comprising chemically modifying a surface of the inner wall after successive activation, silanisation and amidation reactions or after a click chemistry reaction.

A thin film microextraction (TFME) device for preconcentrating a sample in analytical chemistry, the TFME device comprising:

• a glass body having an inner wall, and
• a coating of formula —Si—O—R-M-MOF covalently bonded to the inner wall in an inverted radial manner,
• where MOF is a metal-organic framework,
• where M is a metal dependent on a type of the MOF, and
• where R is an intermediate compound selected from the group consisting of:
• —Si—(CH2)3—NH—CH(═O)—(C6H4)—COO—;
• B) —Si—(CH2)n—NH—CH(═O)—(CH2)2—(C2HN3)—(CH2)n—(C6H4)—COO—;
• C) —Si—(CH2)n—O—CH2—CH(—OH)—CH2—NH—(CH2)n—(C6H4)—COO—;
• D) —Si—(CH2)n—S—(CH2)2—(CH2)n—(C6H4)—COO—, with an n which can take values between 0 and 6.
